When prompted, confirm the change you are about to perform. The
update utility transfers the firmware image to your GPIB-ENET/100
and displays the status of the update, including whether the firmware
update completed successfully or failed. The GPIB-ENET/100
automatically reboots with the new firmware in effect.

PWR/RDY LED Signaling
The
PWR/RDY
LED blinks slowly in a distinct red/yellow pattern to alert
you of internal errors. Use this section to interpret and record the pattern
that the
PWR/RDY
LED flashes, and then contact National Instruments.
Note
By recording the
PWR/RDY
LED status messages before calling National
Instruments, you can save yourself time, and the Product Support Department can answer
your questions more accurately and efficiently. Do not switch off power to your
GPIB-ENET/100 before recording the flashing
PWR/RDY
LED pattern.
PWR/RDY
LED signaling can report up to 81 different errors. The errors
are numbered from 11 to 99 and are reported through sequences of
PWR/RDY
LED flashes.
Note
There is no zero in any error message. This means that error message numbers 0–10,
20, 30, 40, 50, 60, 70, 80, and 90 are not possible.
Step 1. Count the Long Flashes
A three-second interval, during which the
PWR/RDY
LED is yellow,
separates each repetition of the sequence. The sequence begins with a
series of long one-second flashes—that is, one second red, one second
yellow. These long flashes represent the digit in the tens column. There
can be one to nine long flashes, which represent digits 1 through 9. For
example, one long flash represents the digit 1 in the tens column, and nine
long flashes represent the digit 9 in the tens column.
Step 2. Count the Short Flashes
The long flashes are followed by shorter flashes; each short flash lasts
about one-fifth of a second—that is, one-fifth of a second red, one-fifth of
a second yellow. These short flashes represent the digit in the ones column.
Again, there can be one to nine flashes, which represent the digits
1 through 9. For example, one short flash represents the digit 1 in the ones
column, and nine short flashes represent the digit 9 in the ones column.
